SFECIFICATION forming part of Letters Patent No. 539,942, dated May 28,1895.

Application filed February 28, 1893- Serial No. 464,093. (No model.)

To all whom it may concern.-

Be it known that I, MAURICE HELLWIG, of Brooklyn, county of Kings, andState of New:

York, have invented certain new and useful Improvements in Brushes, ofwhich the following is a specification. 1

My invention relates to brushes and to the;

method of making the same.

The main objects of the invention are to provide an improved brush, anda more economical and efficient method for filling and making suchbrushes than the methods now in use.

The improvement in the brush consists in a new construction ofprotecting device thereo the reverse direction, bringing the enlargedadhesive ends into the larger ends of the holes, where they are firmlyheld.

In the drawings, Figure 1 is a side view, partly in section, of apainters or domestic brush. Fig. 2 is a similar view of a modified formof brush. Fig. 3 is a perspective view of a hair-brush with a partbroken away. Fig. 4 shows a brush-back in section and tufts in differentstages therein. Fig. 5 is a perspective view of a difierent form ofbrush and having a protecting-cap. Fig. 6 is a sectional View of thesame. Fig. 7 is a view of the cap detached, and Fig. 8 is a sectionalview of another form of brush.

In Fig. 1 is shown a brush. back B, in which are formed conical ortapering holes 0, converging from behind forward, in which the hair orbristles forming the tufts D, are socured; the back after being filledbeing mounted on the flat enlarged end of handle A, of a form common inpainters brushes. The handle forms a cover for the back and prevents thetufts being pushed out. The cement and the enlarged tuft ends wedged inthe tapering holes prevent the bristles from being pulled out forward.

Fig. 2shows a similar brush. The handle A has a flange 1), forming adepression a, into which the back B, holding tufts D, fits.

Fig. 3 shows a hair brush with a handle A integral with the back holdingthe tufts D In Figs. '5 and 6 the handle A is integral with the partforming a cover for the brush back B and has a flange b forming adepression a for reception of the back. The distal end of this brush isprovided with a cap K of soft non-abrading material, which gives afinished appearance to the brush and protects articles finished, and mayalso aid in holding the back and covertogether. The

holes L (Fig. 7) in the cap are arranged so thatthey register with someof the holes of the back, see Fig. 6, and the tufts D project throughholes L. The back and cover are preferably reduced, as at 1%, so thatthe cap is flush with said parts.

In Fig; 8 back B holding bristles D has a cover consisting of a plateHwithout a handle.

Fig. 4 shows a back B with tufts as they would appear at differentstages in the man ufacture of the brush. The tufts d have been simplyinserted; tufts e have been enlarged by application of cement; andtuftsf, after being thus enlarged, have been pushed back into thetapering holes. 0 are tapering holes without tufts therein.

In the manufacture of a brush the tufts will never appear simultaneouslyas shown at d, e, andf, butwill so appear successively.

The bristles are inserted according to my method in any of the brushesshown, or in brushes of other forms, as follows: The tapering holes areformed in the brush back, and the back is supported with the smallerends of the holes on the upper'side. A mass of untufted bristles orsimilar material is supported in an upright position above the back in asuitable receptacle, and the bristles that are in line with the holesare then, by continued and violent jolting, caused to work forward fromthe mass of bristles into said holes. The jolting is preferablyperformed by the machine set forth in my Patent No. 506,397, datedOctober 10, 1893, but this particular machine is not essential.

It is found that bristles can be inserted much more easily andsatisfactorily from the small ends of the tapering holes than into cy-ICO lindrical holes, or into the large ends of the tapering holes,particularly when jolting them in, probably because it allows thebristies to spread a little after entering the holes, thereby reducingfriction, which is not the case with cylindrical holes. If the largerends of the holes face the mass of bristles more bristles will enter thelarger ends than can pass out of the smaller ends. I-Ienceirregular andimperfect tufts, and in some instances no tufts, will result.

The cement or adhesive material is preferably applied by dipping therearwardly protruding ends of the tufts into liquid cement and causingit to workin among the bristles.

,All the tufts are then pushed back until their ends are flush with therear side of the back. Any one of the covers described, or a substantialcoat of paint or lacquer, is then placed over said side of the back.

I claim 1. The combination of a brush back, having holes with bristlesin them, a cap on the part of the brush back liable to be struck againstarticles brushed, extending over some of theholes of the back, and tuftsof the brush passing through holes in the cap.

2. The improvement in the method of filling perforated brush. backswhich consists in working the hair or bristles into the holes from thefront so that the tufts project from the rear of the back, applyingadhesive material to said projecting ends, and then forcing the tuftsforward in the reverse direction to that of their entrance, bringing theadhesive ends into the holes.

3. The improvement in the method of filling brushes which consists informing conical holes in a brush back, insertingtufts through said holesfrom the smaller ends thereof, en-

larging the ends of the tufts and making them adhesive by working cementinto the ends of the tufts, and then forcing the tufts in the reversedirection to that in which they enter, bringing the enlarged ends intothe conical holes.

4:. The improvement in the method of filling brushes which consists informing backs with conical holes therein, supporting such backs with thesmaller ends of the holes upward, with bristles above the same, andjolting the bristles into said holes.

In testimony whereof I affix my signature in presence of two witnesses.
